I had a Lawnstar 2800w that I bought in I think 2008. Sold it today on facebook in still mostly a 99% working condition. It was missing a bolt that I somehow lost after taking the motor to the lawnstar factory shop to have the shaft, or I think the blade connector refitted, which I think had to be pressed back on.
Anyways only 2 things in that whole time broke that needed replacement.
1. the switch, where something inside melted, and I think it was my mistake for overworking the motor
2. the blade on the shaft came lose and they were happy to fix for a small fee
I;d say that was a good running and the buyer today was happy with his purchase. The motor was still going 100% and the mower stood its whole life in a garage. Only downside, it was also used by my gardener which is can be rough on machines.
If I were to buy again, I would definitely consider a lawnstar again. It does help that there is a factory shop in Epping here in CPT.
Only reason I sold it, not using it anymore and wanted the space back in the garage.
